Honda Fit: Mainshaft Assembly Clearance Inspection (M/T)

NOTE: If replacement is required, always replace the synchro sleeve and the synchro hub as a set.

1. Support the bearing inner race with an appropriate size socket (A), and push down on the mainshaft (B).

2. Measure the clearance between 2nd gear (C) and 3rd gear (D) gears with a feeler gauge (E).

   • If the clearance exceeds the service limit, go to step 3.

   • If the clearance is within the service limit, go to step 4.

   Standard:	0.06пјЌ0.21 mm (0.003пјЌ0.008 in)
   Service Limit:	0.33 mm (0.013 in)

3. Measure the thickness of 3rd gear.

   • If the thickness is less than the service limit, replace 3rd gear.

   • If the thickness is within the service limit, replace the 3rd/4th synchro hub and the 3rd/4th synchro sleeve as a set.

   Standard:	27.92пјЌ27.97 mm (1.0992пјЌ1.1012 in)
   Service Limit:	27.85 mm (1.0965 in)

4. Measure the clearance between 4th gear (A) and the 4th/5th gear distance collar (B) with a dial indicator (C).

   • If the clearance exceeds the service limit, go to step 5.

   • If the clearance is within the service limit, go to step 7.

   Standard:	0.06пјЌ0.19 mm (0.003пјЌ0.007 in)
   Service Limit:	0.31 mm (0.012 in)

5. Measure distance of the 4th/5th gear distance collar as shown.

   • If the length is not within the standard, replace the 4th/5th gear distance collar.

   • If the length is within the standard, go to step 6.

   Standard:

   24.03пјЌ24.06 mm (0.9461пјЌ0.9472 in)

6. Measure the thickness of 4th gear.

   • If the thickness is less than the service limit, replace 4th gear.

   • If the thickness is within the service limit, replace the 3rd/4th synchro hub and the 3rd/4th synchro sleeve as a set.

   Standard:	27.02пјЌ27.07 mm (1.0638пјЌ1.0657 in)
   Service Limit:	26.65 mm (1.0492 in)

7. Measure the clearance between the 4th/5th gear distance collar (A)   and 5th gear (B) with a dial indicator (C).

   • If the clearance exceeds the service limit, go to step 8.

   • If the clearance is within the service limit, go to step 10.

   Standard:	0.06пјЌ0.19 mm (0.003пјЌ0.007 in)
   Service Limit:	0.31 mm (0.012 in)

8. Measure the length    of the 4th/5th gear distance collar as shown.

   • If the length    is not within the standard, replace the 4th/5th gear distance collar.

   • If the length    is within the standard, go to step 9.

   Standard:

   24.03пјЌ24.06 mm (0.9461пјЌ0.9472 in)

9. Measure the thickness of 5th gear.

   • If the thickness is less than the service limit, replace 5th gear.

   • If the thickness is within the service limit, replace the 5th synchro hub and the 5th synchro sleeve as a set.

   Standard:	28.92пјЌ28.97 mm (1.1386пјЌ1.1405 in)
   Service Limit:	28.85 mm (1.1358 in)

10. Measure the length of the MBS distance collar.

    If the length is not within standard, replace the MBS distance collar.

    Standard:

    12.00пјЌ12.05 mm (0.4724пјЌ0.4744 in)
